292 Dislocation; Subluxation articular surfaces of the joint, whereas subluxation is only a partial displacement in the joint. Both dislocations and subluxations refer to the position of the distal bone in relation to its proximal articulation. Although dislocation or subluxation can affect any joint, the most frequently occurring sites are the thumb, elbow, shoulder, wrist, finger, knee, and hip.

When dislocation or subluxation is a result of trauma, there are generally associated injuries to the blood vessels, nerves, ligaments, and soft tissues that surround the joint. In addition to the actual damage at the joint, tissue death from circulatory compromise to the distal extremity, or permanent nerve damage from edema, can occur. Avascular necrosis (death of bone cells because of inadequate blood supply) may occur if the bone is torn away from its normal position next to the vascular-rich bony surface.
